BOTTLE-VALVE MOUNTING. 7

pourout closure of a type which serves not' only as means for sealing the bottle when not in use but also serves to constitute a means for delivering a stream of liquid, such as ink, from the bottle while permitting a free flow. of air into the bottle to take the place of the displaced liquid and the present disclosure constitutes an improvement in devices of the character disclosed 111 my Patent No. 1,314,489, patented August 26, 1919.

In the patented device there was disclosed a valve seat and a nozzle valve rotatably mounted thereonand the parts of which were formed of a composition'capable of being readily molded. In this disclosure the nozzle was held in rotatable relation to its seat by means of a retaining ring having the same composition as the nozzle. A h gh degree of care has to be exercised in capping the bottles with this device to insure against a binding action between the retaining'composition ring-and the composition nozzle.

It is understood that in devices of the character disclosed, it is necessary to insure not only against leakage between the movable parts of the valve but at the same time, to permit a freedom of .nlovement of the movretaining ferrule is positioned on the comable parts. Itis further understood that the commercial forms -of bott1es possess slight variation in sizes and it is physically impossible to provide ,1 the cork washers of unlform size and compressibility. When the mer'cially imperfect-forms of the devices, such as is disclosed in my prior patent, above identified, the ferrule is very apt to exert an abnormallpressure on the nozzle with the result that the nozzle is either difiicultly movable or, on the contrary, it develops a looseness of play which is decidedly ob ectionable. Accordingly, the primary object of this invention is to'provlde a mounting for retaining the nozzle in engagement with its seat and which will permit of the preformation of a pressure between the movable parts which can be accurately controlled and Specification of Letters Patent.

which will be independent of any effect whichmight otherwise be imposed thereon by the mounting of the device on the bottle..

Incidental to the. desideratum of freedom 'of' rotary movement between the nozzle'and Its means for holding it to its valve seat, the invention contemplates the utilization of a metallic retaining means in distinction from the composition retaining means disclosed in the above identified patent, so as-to insure a sliding contacting surface of metal on composition, rather than the relatively high coefficient of friction provided by the interengagement of composition on composition. There is a market requirement in connection with devices of this character that they must be cheaply constructed; a small fraction of a cent saved inmanufacturing cost is vital from a commercial standpoint, and accordingly the present invention features a metallic retaining clip or ring construction which can be cheaply manufactured by a stamping operation and in which the valve nozzle and its seat can be quickly and accurately fastened together to provide a com plete article of'manufacture. It is the intention that this article be stored and sent to the bottle capping machine without any necessity on the part of the capping opera tor to see that the valve parts are in correct my invention shown attached to the upper portion of a bottle neck;

The closure constituting the subject-inatter of this in ention is designed of an article of manufacture for attachment to any kind of a bottle or other receptacle of suit-- able size, and it is arranged to he placed on top of the bottle and fastened thereto by any conventlonal ferrule fastening device.

The upper portion. of such a bottle is shown at 10 in Fig. 1, positioned on top of which is a cork ring Washer 11, constituting a cushioning devic. ment and the bottle to prevent breakage when the bottles are assembled is a capping machine. The Washer is designed to heplaced under sufficient pressure to form a tight seal between the attachment and the bottle. A flat relatively thin disk 12 hereinafter indentiiied as a nozzle seat is fitted Within the ring washer 1.1 and is provided with an upstanding rim 13 positioned on top of the Washer to form an angle joint with the Washer. The nozzle seat is outlined by a free peripheral edge 13 adapted'to he engaged by the ferrule for securing the device to the bottle as hereinafter described. T he top of the nozzle seat Within the inelosing rim is fiat so as to provide a smooth bearing surface 14. The nozliquid passageway 21 designed in one posi-- tionof the nozzle to 'aline' with the opening 15, to provide a liquid conduit from the interior to the exterior of the loot tie. The nozzle is also provided with a straight, air inlet passageway 24- designed, when the passageivay 21! is alined with the opening 15, to aline with the air inlet ope ing '16. In this Way when the nozzle is in position permitting the discharge of the. J

The article of manufacture thus defined is fastened to the bottle by any suitable means, such for instance, as by means of the usual metal ferrule 40 which is in overlapping engagement with the seat rather than inoverlapping engagement with the retaining ring as shown in my patent, above identified. As the retaining ferrule is thus spaced from the means which holds the nozzle to the seat,

' it is appreciated that any abnormal pressure exerted by the capping machine will simply compress the washer 11 more or less and any such pressure, or, on the contrary, lack of pressure, will have no effect whatsoever upon the present compression of the gasket 20.

It is noted that in the disclosure in Fig. 1, the right hand clip is of less height than the left hand clip, so that in this instance the smaller clip with its upper flange positioned onthe groove 39 constitutes a means for limiting the rotary movement of the nozzle on its seat. This simple metal clip arrangement provides a cheap construction for' effecting this limitation to rotary movement of the nozzle and in the form of the retaining means disclosed in Fig. 5, this same effect is produced by the depression 38 in the ring. Another way of regarding this structure is to consider that the depressed portion 38 and the shank portion 32 immediately therebelow is the equivalent of the single clip shown in Fig. 4 and the rest of the ring is simply an enlargement of the left hand clip of Fig. 1.

VVhile- I have shown anddescribed, and

have pointed out in the annexed claims, certain novel features of my invention, it will be understood that various omissions, substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
